ORE-CONCENTRATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 537,756, dated April 16, 1895..

Application led March 23,1894.

To all whom t may concern:

Be it known that I, GUsTAvIs LORRIMER OUDNER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Ore-Concentrating Apparatus, of which the following is a specification.

The ore concentrating apparatus forming the subject of this invention is capable of lro working in such placers or localities where the water supply is limited and where there is no fall convenient for tailing off dbris, and the invention consists in the novel features of construction set forth in the following specilication and claims and illustratedV in the annexed drawings, in which- Figures 1 and 2 represent a sectional elevation of the plant. Fig. 3 is a plan View of part of Figs. l and 2. Fig. 4 is an elevation zo of a blanket table sectioned along oc Fig. l. Fig. 5 is a plan view of a screen sectioned along y y Figs. l and 2. i

The endless railway lis constructed so that the track is all down grade except a short disz 5 tance, where the cars are carried up the grade by a cable or belt system.

A is the head Wheel for the cable; B, the foot wheel; C, the idle pulleys; D, the cable or link belt.

The railway is provided With dump cars or buckets E.

The steam shovel 2 is on a separate track F.

The boWlder screen 3 comprises a hopper G and a coarse screen H mounted on wheels I.

The disintegrating tank 4 is of the shape shown in the drawings, with a partition J, a coarse screen K, elevator chain and buckets L, head wheel M, foot wheel N, with a driving pulley P and a sluice-way Q.

The disintegrator is supplied with water by the pipe R from the upper Water tank 9.

The elevator L is rotated by means of a belt O extending from the line shaft X to the pulley P. A ne screen 5 works in a tank of water S.

The tank'is of'the shapeshown in the drawings. The screen 5 is suspended by four rods T. The screen has four motions by means of the cam or crank U which is on the vertical i shaft V. On the upper end of the screen 5 is sain No. 504,827. (N6 man.)

5o an attachment or lug W. A vertical shaft X passing through the attachment W is pivoted in the step Y and connected with the crank U at the top. The shaft V is rotated by means of the belt O from the pulley a on the counter shaft Z. g

The elevator 6 which raises the coarse dbris coming from the end of the screen 5 into the receiver b has a head wheel c and a foot Wheel d, chain and buckets c and a driving pulleyf 6o which is rotated by means of the belt- 02 from the line shaftX. The receiver o has a gate j and a lever 7c. The screen tank S has rotating chains g which pass around pulleys h and which aid the fine matter which has passed through the screen 5 in the tank S to discharge into the trough fi. The chains g are rotated by means ot' the driving pulley n connected by beltvO3 with the line shaft X. Near the top of the screen tank S is a pipe mi which is for the purpose of discharging water and slimes.

The precipitator and amalgamator 7 is a tank having an inclined iioor P with a partition A and a partition K. At the bottom of the partition A is an iron guide H. At the lower end of the floor P is a movable plate or door F. At the top of the tank is a shaft V with sprocket wheels R and a shaft S with sprocket Wheels R2, and on the end of the shaft S is a driving pulley P2. There are a number of endless cable chains N which pass around the sprocket Wheels R R2 and around the guide way H. By means of a belt O4 connectedwith the pulley P2 and the shaft Z the chains N are actuated.

Pipes H2 conduct the pulp from the trough i to the precipitator 7.

The automatic blanket table 8 is a frame work with inclined floor B. It has three long rollers running lengthwise P2'E2 D. Fastened to the belt A2 are lags or slats of iron or wood B2 running lengthwise parallel with the rollers. The slats form narrow gutters upon the table M A shaft H3 runs length- 95 wise of the table with two arms R2, lever F2, brace Y and two latches S2. On the lever F229 is a Weight T and at the end is a crank wheel W which is on the end of the shaft G. In the crank wheel W is a pin Cl and the shaft G is actuated by bevel or'driving gears Y2.

' A beam J runs lengthwise of the table and is provided with arms J2 and N2 pivoted thereto and a connecting rod B2 which connects with a crank E at the end of theshaft V of the precipitator 7. At the bottom ends of the arms N2 and J2 is a perforated pipe K2 running lengthwise of the table. At the end of the pipe K2 is a rubber hose a connected With the water pipe L. At the lower side of the inclined oor B is a receiving trough X2. There are gutters U which conduct the pulp from the precipitator to the blanket table.

Thesystemis operated asfollows: By means of the steam shovel 2 the material is scooped up and thrown upon the-bowlder screen 3 whichthrows off the coarser matter. -T-heiiner material then passes through the screen into the dump carE. The car E passes by gravity down the railway 1. When the car is elevatcd by cable D or otherwise the material is dumped upon the screen K of the disintegrator 4. The water from the pipe R ilows upon the material and washes it down through the screen K. The water flows down the sluice Q and the material is lifted up by thev elevators L and d umped into the sluice Q, whence it runs down upon the screen 5. Thetine matter passes through the screen-into the tank S, the coarse dbris being carried up'by the elevator 6 into the receiver b whence it is dumped into the car E by opening the-gatej by means of the lever k. Thecar isloaded from the receiver and passes down theiuclined track and the coarse dbris is dumped at any suitablepoint as into an arroyo. The tine matter which has passed through the screen 5 into the tank S is by means of the rotating chains g carried with part ofthe water to the troughz' whence it passes down through thepipes H2 into the precipitator and am-algamator 7. The precipitator has a quantity of pebbles I which are kept partly in suspension by the upward motion of the chains N which brightens amalgamates and precipitates the precious metal. The amalgainator 7 is kept supplied with mercury as required for amalgamation. The dbris passesfrom the precipitator 7 down the gutters Uupon the blanket table where it passes down the gutters or spaces between the slatsB2and out through the discharge or gutter S2. The tine matter which has been received by the precipitator 7 carrying gold and fine particles of ore of value which has not amalgamated and=pre cipitated, has flowed out upon the blanket tableand settled in the ssures. `The shaft G revolves slowly. The pin C in thewheel W lifts the lever F2 and by means of the larms R2 the latches S2 are movedforward so that they hook on to a strip B2. When vthe lever F2 is released from the pin C the weight T causes the lever to fall upon the stop or beam O5 thus moving the entire blanket upon table M the distance between two adjacent strips B2. rI-hisl brings another'one of the spaces between two strips B2 containing value and some remaining light matter opposite the small tank O6 at the head of the table. This tank is supplied with -water which runs thence onto blanket A2 and the light matter is thus washed off the blanket down into the discharge gutter S2. As the belt A2 moves a space regularly at every revolution of the wheel W the perforated pipe K2 swings on arms N2 and J2 by means of the connecting rod B3 and crank E. The water flowing from the perforated pipe K2 upon the nearly perpendicular side of the blanket or belt A2, washes from the fissures or spaces on the blanket the concentrated value down into the trough X2. The coarse dbris beingv dumped below the plant andthe fine dbris and water being discharged above the coarse dbristhe water will filter through the coarse debris and run down into thefcistern lOwhence it is pumped up into the upper water tank 9 to be again used. This feature of the vsystem enables the work to be carried on with little loss of water.

The cistern l0 is placed at a low, or preferably the lowest point of the plant, so that vthe Water from-any arroyo or other source will descend into the cistern.

I have found it to be of advantage to pro- -vide theprecipitator and amalgamator 7 with two upper rollers AR R2 as thereby the chains N are spread and prevented from bunching or clogging at the bottom of the precipitator, by which bunching or clogging interruption or breakage might be caused.

Themanner of raising cars E is of course immaterial as these cars can be either run up an incline by cable D or raised byany suitable elevator or lift.

.What I claim as new, and desire to secure by Letters Patent, is-

l. A case or frame provided with a table M', an inclined bottom B and rollers D E2 P2, combined with a belt made to travel about the rollers, strips B2 secured to the belt, a pawl or catch S2 made to engage the strips and an actuating lever for the pawl substantially as described.
